Also, calibration impossible since before they occur enables the preparation of maintenance and parts arrangements, quickly perform the process after calibration impossible occurs. further, by confirming whether the suspicious condition is approaching what extent the calibration impossible range of the normal range, calibration it also becomes possible to make predictions of the non-occurrence time.

【0018】上述の実施例においては、ガス分析装置の校正演算時のゼロ校正係数の範囲を判定するようにしていたが、この発明は、これに限られるものではなく、スパン校正係数や干渉補正係数の範囲を判定するようにしてもよいことは勿論である。 [0018] In the embodiments described above have been possible to determine the range of zero calibration factor during calibration operation of the gas analyzer, the present invention is not limited to this, the span calibration coefficient and interference correction that the range of the coefficients may be determined as a matter of course.

【0019】また、この発明は、上記ガス分析装置のみならず、他の分析装置にも適用できることはいうまでもない。 Further, the invention not the gas analyzer only, the present invention can be applied to other analyzers.
